Controller Operation
The controller uses a set of digital LED displays to
show various temperatures as well as status and
alarm conditions.
Start
To start the unit press the Start button. If the oil level
in the reservoir is too low, the display will show
F I L L
and the Low Level Alarm Indicator light will turn on.
The Low Level Alarm Indicator light will remain on
until the oil level is sufficient for operation.
Oil becomes thick and is hard to pump when it is
cool. To protect the pump from stress at start-up the
unit will only start the pump if the temperature in
the tank is above 68°F. If the unit starts and the oil
temperature in the tank is below 68°F, the heaters
will come on; however, the pump will not run. When
the oil temperature is above 68°F the pump will turn
on and the heaters will heat the oil until the oil
temperature reaches 85°F. While in the initial heat-
up mode the display will only show an
A
indicating
that it is in an alarm mode and not in a running
mode.
Above 85°F, the unit enters a normal operation
mode. The status display will show a
1
and the
remaining digits will show the tank temperature. The
heaters and pump remain on until the pump bearing
reaches 250°F, at which time the controller will turn
off the heaters and continue to run the pump and
the unit will enter into normal temperature control
mode.
Stop
To stop the unit press the Stop button. When the
unit is stops, the status display and the last digital
display on the right will display a dot.
WARNING: Stopping the unit without cooling the oil in
the reservoir can lead to potential user injury during
servicing of the unit. In order to allow the oil in the
reservoir to cool automatically during shut down,
depress the Temperature Adjust button and the
Password ‘C’ button to initiate an automatic cool
down cycle. The controller will open the cooling valve
and keep it open until the temperature of the oil in the
reservoir is below 120°F. To stop the automatic cool
down cycle at any time depress the Stop button.
Temperature Adjust
The Temperature Adjust button is used to view and
change the set point temperatures.
Display Set Point Temperature
To display the Set Point temperature press and
release the Temperature Adjust button. This will
show the Set Point temperature in the display. If no
other buttons are pressed for 5 seconds, the display
will return to the actual temperature.
Setting Set Point Temperature
To change the Set Point temperature press the
Temperature Adjust button and release to display
the current Set Point temperature and then
immediately used the Increase or Decrease buttons
to change the Set Point temperature until the
desired temperature is displayed. Once the desired
Set Point temperature displays, release all buttons.
After 5 seconds, the display will return to the actual
temperature and the new set point is active.
Increase
Pressing the Increase button increases the value of
the set point, deviation alarm, and timer settings
when those adjustment features are active.
